Hackers Exploit JFrog Artifactory Flaws to Bypass Authentication and Gain Admin Access

Wiz Research observes multiple attackers exploiting three JFrog Artifactory flaws, including default-configuration authentication bypass CVE-2026-82329, to gain admin access and deploy backdoors.

Attackers chain CVE-2026-42018 and CVE-2026-42016 to exchange anonymous JWTs for administrator-scoped tokens, or exploit CVE-2026-82329 directly via the registry join endpoint to obtain admin privileges under default configuration. Post-exploitation observed by Wiz includes persistent admin users created within five minutes, malicious Groovy plugins for command execution, and Rust-based backdoors dropped to /tmp, /var/tmp, and /dev/shm with C2 communications. Compromise exposes software artifacts, repository credentials, CI/CD integrations, and cluster secrets, creating supply chain risks. Fixed releases include 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, and 7.161.20.

cPanel ConfigServer Security & Firewall Vulnerability Allows Remote Attacker to Execute Arbitrary Commands

CSF 14.00–16.29 (CVE-2026-65638) lets unauthenticated attackers execute arbitrary commands via the MESSENGER service on cPanel/WHM servers; version 16.30 fixes it.

CVE-2026-65638 affects ConfigServer Security & Firewall (CSF) versions 14.00 through 16.29 and allows unauthenticated remote attackers to execute arbitrary commands through the MESSENGER service, running under the unprivileged CSF service account rather than root. Exploitation requires the non-default MESSENGER service to be enabled and a reCAPTCHA secret configured, reducing exposure for standard deployments. CSF 16.30 and later fix the flaw; administrators who cannot update immediately can set MESSENGER = 0 in /etc/csf/csf.conf as a temporary mitigation.

One in four MCP servers opens AI agent security to code execution risk

Noma Security whitepaper finds most popular AI Skills and many MCP servers carry high-risk capabilities, with state changes most prevalent.

Noma Security analyzed hundreds of popular MCP servers and Skills across eight risk categories, finding most widely used Skills carry at least one risky characteristic and a typical enterprise runs well over a hundred high-risk agent tools, with arbitrary code execution common across MCP servers. The most prevalent risk is the ability to change state or data, and named toxic combinations include ContextCrush data leakage, ForcedLeak via poisoned Salesforce CRM records, DockerDash supply-chain compromise, the Replit production database deletion, and the hijacked Amazon Q VS Code extension. Building on OWASP LLM06:2025, the paper proposes the No Excessive CAP framework of capabilities, autonomy, and permissions, recommending allowlisting, MCP version pinning, approval gates on irreversible actions, and user-scoped expiring credentials.

Surfshark VPN says hackers breached internal testing, proxy servers

Surfshark disclosed that hackers accessed misconfigured internal test and proxy servers, exposing build credentials but not customer data, VPN traffic, or production infrastructure.

Surfshark said a human error left an internal engineering test server reachable from the internet, exposing service configurations, build-related credentials, and portions of system binaries and code history. A separate proxy server used for content-accessibility optimization was also accessed, but it stored no user identity data, IP addresses, encryption keys, or browsing traffic. Suspicious activity was detected on August 31, contained on September 2, and remediation completed on September 5, with no evidence of credential misuse or spread to other systems. The company rotated impacted credentials, revoked exposed tokens, added monitoring and hardening, and commissioned an independent infrastructure audit; no customer action is required.

Hackers Disable Endpoint Protection and Deploy Sliver Across Compromised Windows Domain

The Hunter's Ledger tracked campaign UTA-2026-024 using Sliver C2, Domain Admin account creation, and Ethereum-based C2 rotation to compromise a US organization's Windows domain.

The Hunter's Ledger tracked an intrusion at one unnamed US organization as UTA-2026-024, staged from exposed server 193.233.202.17 with a Sliver beacon. Operators created a non-expiring Domain Admin account, enabled RDP with NLA disabled, dumped SAM, SYSTEM and SECURITY hives plus LSASS memory, and disabled eight endpoint protection services. A Node.js implant resolved its C2 server from an Ethereum smart contract that rotated domains five times in five months, while SYSTEM scheduled tasks with backdated dates and DNS allowlist manipulation provided persistence. The infrastructure ties to a confirmed ransomware incident, but no encryptor deployment was proven in this intrusion.

From Infostealer Log to Marketplace Listing: A Technical Walkthrough of the Credential Theft Pipeline

Cyble walkthrough maps how infostealer logs move from endpoint infection through aggregation and enrichment to dark web credential marketplace sales.

Cyble breaks the credential theft pipeline into stages: infostealer execution harvesting browser credential stores, cookies, session tokens, crypto wallets, and FTP configurations; aggregation of stealer logs via C2 panels into bundled archives; parsing and enrichment against previously leaked datasets; and final listing on dark web marketplaces. Enrichment adds employer and role context that raises prices and enables credential stuffing across reused passwords. The report advises SOC teams to monitor stealer logs and marketplace chatter early rather than waiting for breach alerts.

Hackers Impersonate IT Support on Microsoft Teams to Take Control of Employee PCs

Microsoft warns of a human-operated campaign where attackers pose as IT support in Teams to gain remote PC control and reach domain controllers.

Microsoft Threat Intelligence observed attackers abusing Microsoft Teams external collaboration to impersonate IT/helpdesk staff, persuading employees to grant screen control via Quick Assist or RMM tools. Operators deploy malicious MSI packages via silent msiexec, run encrypted JavaScript implants through portable Node.js, and persist via EdgeUpdate Run keys or Startup folder entries. The Node.js backdoor uses HTTPS long-polling C2, captures screenshots, enumerates Active Directory, and moves laterally over WinRM (TCP 5985) to domain controllers and certificate authorities. Initial access maps to MITRE ATT&CK T1566.003 (Spearphishing via Service); no Teams vulnerability is exploited.

Almost Half of Malware Samples Communicate Direct to IP

Unit 42 analysis of 4 million malware reports finds 45% of C2-active samples connect directly to hard-coded IPs, bypassing DNS defenses.

Palo Alto Unit 42 analyzed over 4 million Advanced WildFire dynamic analysis reports and found that 45.32% of malware samples with C2 activity made at least one direct-to-IP connection, accounting for 23.17% of all C2 connection attempts. The firm proposes zero trust IP (ZT-IP), an enforcement approach that verifies whether outbound destinations were ever sanctioned by a DNS response. ZT-IP analysis surfaced Phorpiex ransomware droppers fetching payloads directly from C2 IPs, a persistent data exfiltration campaign using an obfuscated \GET protocol, and Mozi P2P botnet payloads delivered to IoT devices without DNS. Only 1% of benign samples connected directly to untrusted IP addresses.
